Hello Bebefromnc,

Congratulations on your new iPhone 5!  If you are trying to sign into the iTunes and App Store with your Apple ID, you can use these steps:

Changing your Apple ID account

Tap Settings > iTunes & App Stores, then tap the Apple ID signed in.

Sign out of the current Apple ID account and then sign in with another account or create a new Apple ID.
